We
mainly use Propellerhead Reason 4 which is a complete studio plenty
of virtuals racks you can feed with your favorite gear : analoglike
synth, granular synthesis, sampler, loopsplayer, mixer, effects,
drummachine, groovemixer, to name few...It's a complete solution
in an unique and versatile package. Reason does'n't record audio,
so you will need a software ( there are good freewares right here)
to record vices or real instruments you will later re-add in Reason
4 via the NNXT sampler for instance. With multiple banks available
on the web you will quickly own some thousands of sounds, modules
and loops - REX files- ready to serve your inspiration. The perfect
nomad instrument.
